Report from SemTechBiz + Getty TGN in nomisma.org

I spent last week in San Jose, attending the Semantic Technology and Business conference, where I participated in a LODLAM-sponsored workshop aimed at providing an introduction to linked open data technologies to a library, archive, and museum audience.

I was asked to provide a somewhat hands-on demo of SPARQL. My presentation, from 0 to 60 on SPARQL queries in 50 minutes provided a brief outline of the sorts of linked data methodologies we're employing in our numismatic projects--particularly nomisma.org and OCRE--and the SPARQL queries that make them possible. I started fairly simply and built up to more complex queries of weight analysis and geographic distribution of coin types. By downloading SPARQL queries with geographic data as a CSV file from the nomisma.org endpoint, I was able to import the CSV directly into Google Fusion tables to generate maps. I have placed the content of the slideshow up on Dropbox as a PDF.

The audience consisted mainly of cultural heritage professionals, although there were some industry professionals in attendance. The feedback I received was positive overall (judging by the Twitter stream, in any case), but I did receive comment about the model and ontology (or lack thereof) that we have employed in nomisma.org. Rest assured that we are working on a formal ontology and refined data model that conforms to data/computer science standards. No more URIs used simultaneously as classes, properties, and instances!

On another note, the Getty Museum announced last week the release of their Thesaurus of Geographic Names as linked open data (following the Art and Architecture Thesaurus). I have extended the nomisma editing interface (as well as the Kerameikos.org one) to enable Getty TGN lookups for mints and regions in order to link nomisma ids with Getty ones. Through this mechanism, we can establish links between Pleiades and TGN places, although there are certainly more ancient places in Pleiades than in nomisma, which are purely numismatic.


The text search yields a response of matches from the Getty SPARQL endpoint. The user can read the scope note for further context about the use of the TGN id and make the appropriate selection of skos:exactMatch or skos:relatedMatch.

Art of Devastation: A Web-based Catalogue of First World War Medallic Art

As part of its commemoration of the centennial of the First World War, the American Numismatic Society announces the launch of Art of Devastation (http://numismatics.org/aod/) an important new web-based research catalogue of the thousands of art medals, commemorative medals and tokens produced in response to this major conflict.

Directed by Dr. Peter van Alfen, with assistance from Sylvia Karges, Art of Devastation aims to be the first comprehensive catalogue of this abundant and varied material, one that takes full advantage of the web environment and linked open data. Intended to help identify medals and tokens in users’ hands, Art of Devastation offers unique catalogue numbers for types and variants for future referencing, and illustrates, where possible, multiple examples for comparison. Mapping tools allow users to locate where the item was created, and where the events associated with it took place. Links to other websites, such as Wikipedia, take users to entries discussing the artist who created the item, as well as the people, events, and things, like the weapons or symbols depicted on it. In addition to serving as an identification and learning resource, Art of Devastation provides easy access for non-numismatists to an important, yet often overlooked body of primary evidence from the Great War.

Before the War began, medals and tokens had served for centuries as a significant means of communication where easy and durable forms of mass communication did not exist. Whether issued by states, organizations, or individuals, their commemorative and propagandistic function was already well known and understood. Increasingly, by the turn of the century, the medal had also become an important medium of more reflective and private artistic expression. Art medals could be distinguished from traditional types of medals by their frequent lack of words, non-elite representation, greater emotional intimacy, experimental shapes, and cast production rather than striking. During the War, these various public and private functions continued, converged, and were greatly intensified by the enormity of the conflict. Thousands of different types of medals and tokens were produced on both sides, consuming scarce metallic resources. This outlay underscores the fundamental role that these items played in feting heroes, marshaling support, directing public opinion, and, more poignantly, expressing grief and disgust.

Art of Devastation enables users to explore the range of artistic responses to the War and particular events within it. The sinking of the Cunard passenger liner RMS Lusitania by the German submarine SM U-20 on May 7th 1915, for example, attracted considerable artistic output on both sides of the conflict. René Baudichon, a French artist, responded with a medal with themes paralleling those of Allied atrocity propaganda, depicting a drowning child avenged by Ultrix America, the Statue of Liberty with a sword.

On the German side, the emotions were more complicated. The artists Karl Goetz and Walther Eberbach derided Allied hypocrisy on purported bans on armament shipments on passenger liners with their satirical takes on the sinking, while Ludwig Gies cast enmities aside to focus solely on the human tragedy of the event.

The creation of this new web tool is the work of ANS database developer Ethan Gruber. At launch, Art of Devastation incorporates the roughly 1,400 relevant items in the ANS’s collection. In collaboration with other institutions, such as the Staatliche Museen zu Berlin, the Royal Library of Belgium, and the Kunsthistorisches Museum in Vienna, the catalogue will continue to expand.
